Ear Phone Extensions A guitar pickup is actually similar to a dynamic microphone coil. For many years, powerful microphones have already been sent with the style coil attached with the primary of the microphone's transformer, and not referenced to ground (‘floating'). The microphone's case is normally linked to the wire guard, which is connected to the mike amplifier's floor (see Rane's internet site for more discussion).
By and large, dynamic microphones are very calm products as a result of the combination of transformer isolation and balanced, floating indication lines throughout, as well as shielded, humbucking coils.
So why not instruments? Guitars are notoriously plagued by noise. Humbucking pickups are only an incomplete (though crucial!) solution. The obvious option is always to float your guitar pickup to a healthy result, just like a microphone. A similar thought was published that 2001 patent software such as Ear Phone Extensions?
